  • the air gap must be chosen so large that these tolerances can be compensated, or contact between the parts is prevented with certainty. This in turn significantly affects the efficiency of the fan, because the power losses caused by the gap being too large are enormous.
  • auxiliary blades and blade extensions do not provide sufficient remedy, because with a larger distance or gap, the distance between the auxiliary blades also increases, which significantly reduces their effect.Reliable covers are used here, which can reduce the losses due to the larger air gap - but they do nevertheless remain enormously large representation of the invention
  • the object of the invention is then to propose a centrifugal fan, in particular as an air fan for the cooling system of a vehicle, which allows significantly greater tolerances between the rotating impeller and the stationary inlet nozzle without significantly reducing the efficiency of the fan.

  • This gap or distance of the air guide ring from the inlet nozzle is provided with suitable covers, which are specified in claims 9 to 11
  • the different versions of the cover depend on which embodiment of the air guide ring is selected.
  • elastic elements for example brushes, rubber elements or the like, are arranged either on the inflow nozzle or on the vertical section of the air line.
  • the other embodiment has a circular part arranged around the inflow nozzle
  • the most economical and most economical type of engine can be selected from the crankshaft of the engine, which has a positive effect on the overall energy balance of the vehicle or the system.
  • the minimal air gap between the cover plate and the air duct that follows causes the gap flow to remain despite possible movements between The fixed and rotating parts are always constant and can therefore also constantly develop their positive effects, which then consist in preventing the surface flow from breaking off at the cover plate. It is also advantageous if this gap between the cover plate and the air duct narrows towards the impeller. because this leads to a nozzle effect, which improves the effect described above.
  • the gap width can preferably be between 2 and 5 mm
  • connection between the cover plate and the co-rotating air duct can be a detachable connection, for example a screw connection, or also a non-detachable connection, for example a welded connection or adhesive connection.
  • Corresponding connecting webs are provided distributed around the circumference
  • the good efficiency of the radial fan is further supported by the fact that the collar-shaped end of the inlet nozzle, which directs the air from the suction side to the pressure side, has a quarter-circle cross section or is somewhat smaller than the quarter circle.

  • the radial fan 1 is driven by the motor 27 of the motor vehicle. In the present case, the torque is transmitted to the radial fan 1 via a V-belt drive 28. In other applications, the radial fan 1 can be connected directly to the crankshaft of the engine 27 via a clutch.
  • the direct drive from the motor 27 to the radial fan 1 is the cheapest option in terms of energy economy.
  • this variant requires a larger distance (gap 18) between stationary and rotating parts because of temperature fluctuations and vibrations caused by the running of the engine lead to changes in position, which must be compensated. Logically, the parts must not come into contact with one another and the performance of the radial fan 1 must not suffer significantly because otherwise it would not be ensured that the projected cooling capacity would also be achieved in phases of greatest cooling demand.

Abstract

L'invention concerne un ventilateur radial, s'utilisant notamment comme soufflante pour le système de refroidissement d'une automobile, qui comprend un rotor (3) muni d'ailettes radiales (4), un disque de recouvrement (5) sous forme de buse, une bague de guidage de l'air (6) fixée dessus, un fond de rotor, ainsi qu'une buse d'admission (8) fixe. Un tel ventilateur radial (1) doit avant tout autoriser une tolérance sensiblement plus importante entre les parties rotatives et les parties fixes, sans avoir pour autant à tenir compte de pertes de puissance sensibles. A cet effet, il est prévu une fente d'aération (10) axiale entre le disque de recouvrement (5) et la bague de guidage de l'air (6) qui tourne conjointement avec lui.
